Why it works: Beans and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 5,242 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Beans
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the beans
Soak the beans overnight in water.
Drain and rinse the beans.
Put the beans in a pot with fresh water and parboil until tender.
Bake
Transfer the beans to a bean pot.
Add the piece of bacon.
Season with salt.
Bake in a preheated oven at 300°F (150°C) until the beans are fully cooked and flavors meld, about 3-4 hours.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Dried beans
- Form the main body of the dish, becoming tender and creamy as they cook.
- Bacon
- Adds fat and smoky, savory flavor that seasons the beans during baking.
The step that matters
Parboil the beans until tender. Dried beans contain compounds that resist digestion and need thorough cooking to soften. Parboiling before the long bake helps ensure they become fully tender rather than remaining firm inside.
